Canyon Offshore Limited, a trenching solutions provider based in Aberdeen, has been awarded a contract by Siem Offshore Contractors for the provision of trenching services on DONG Energy’s Hornsea Offshore Wind Farm Project One.

In November 2016, and building further upon the recent establishment of its UK office in Aberdeen Scotland, Siem Offshore Contractors was awarded a contract for the installation of the inner-array grid cable system for the Hornsea Offshore Wind Farm Project One by DONG Energy Wind Power A/S.

Canyon Offshore’s award will require the trenching of approximately 140 km of inner-array grid cables on the wind farm which will have been laid onto the seabed by Siem Offshore Contractors. In order to provide the optimum trenching solution to bury the inner-array grid cables, Canyon Offshore Limited will use both jetting and cutting methodology with its Jet Trencher, T1200 and its hard ground trencher, i-Trencher. Both systems, together with two work class remotely operated vehicles, will be deployed from a single support vessel, the chartered Grand Canyon I, with operations commencing Q4 2018. Management of the operations will be provided from Canyon Offshore Limited’s Aberdeen base.

Canyon Offshore Limited’s Director for Commercial & Sales, Euan Roberts, says, “We have built up an enviable track record in providing successful trenching solutions to the offshore wind-farm market in recent years in the North Sea, successfully burying hundreds of kilometres of inner-array grid cables. This has complemented our traditional oil and gas trenching market and extended our brand into the renewables industry.”

Siem Offshore Contractor’s Project Manager for the Hornsea One wind farm, Johann Stulemeyer, says, “In Canyon Offshore we will not only have a UK partner to complement our growing local presence, but also a technical leader in their field whose trenching solution will neatly complement our Siem Duo cable lay solution. We look forward to working together.”

Duncan Clark, Hornsea Project One Director says, “The UK leads the world in offshore wind and the industry continues to grow. This is great news not only for our low carbon electricity needs but also for the many skilled suppliers and contractors that are becoming part of this booming supply chain. We are delighted that Siem Offshore Contractors have chosen to work with another UK based company, as a strong and competitive UK supply chain providing the specialist capabilities needed to serve this growing industry will ultimately help to reduce the cost of electricity.”
